Hollywood Matchmaker: Julianne Hough

Why it could work: If the "Safe Haven" actress wants to make her entertainment mogul ex-boyfriend jealous, she needs to go big. And who's bigger right now than Bradley Cooper? The hunky sweetheart with the bad boy image is (somehow) still single, plus Julianne Hough could have a new bestie in Jennifer Lawrence. Not to mention that Bradley's dancing skills from "Silver Linings Playbook" would make him a great partner for Julianne on "DWTS."
